  • COMPARISON OF HETEROTOPIC OSSIFICATION BETWEEN FEMORAL HEAD RECONSTRUCTION AND TOTAL HIP ARTHROPLASTY IN PATIENTS WITH ISCHEMIC NECROSIS OF FEMORAL HEAD

    Objective To compare heterotopic ossification between femoral head reconstruction and total hip arthroplasty(THA) in patients with ischemic necrosis of femoral head(INFH). Methods Between June 1994 and December 2004, the femoral heads were repaired in 1 005 patients with INFH,the total hip was replaced in 485 patients with INFH. The rate of heterotopic ossification was observed in 74 (Ficat Ⅲ to Ⅳ stages) of 1 005 patients and 80 of 485 patients given THA to compared the results of the two methods. Results These patients were followed up 2 to 10 years(6.5 years on average). The rates of heterotopic ossification were 5.4%(4/74) and 22.5%(18/80), respectively. There was statistically significant difference between two operative methods (Plt;0.01). Conclusion The rate of heterotopic ossification of femoral head reconstruction is lower than that of THA, so femoral head reconstruction is a better operative method for young patients and THA is suitable for old patients.

  • EFFECTIVENESS OF A SUTURE BRIDGE TECHNIQUE FOR REPAIR OF QUADRICEPS TENDON RUPTURE IN UEAEMIC PATIENTS

    ObjectiveTo investigate the effectiveness of a suture bridge technique for quadriceps tendon rupture repair in uraemic patients. MethodsBetween March 2010 and September 2012, 10 uraemic patients (14 sides) with quadriceps tendon rupture were treated with the suture bridge technique. Of them, 8 were male and 2 were female, aged from 30 to 62 years (mean, 54.2 years). The duration of uremia was 3-11 years (mean, 5.5 years);the duration of quadriceps tendon rupture was 5 days to 2 months (median, 12 days). Six cases had a trauma history, and one case had diabetes. The left side was involved in 2 cases, the right side in 4 cases, and both sides in 4 cases. The active range of motion (ROM) of the knees was (115.0±8.3)°in flexion, and (72.5±21.2)°in extension. Lysholm score was 19.5±16.3. X-ray films showed downward shifting of patella. MRI revealed discontinuity between distal quadriceps tendon and upper pole of patella. ResultsThe operation time was 30-50 minutes (mean, 40.3 minutes). Primary healing of incision was obtained in all patients without complications. All patients were followed up 12-25 months (mean, 16.3 months). There was no re-rupture of quadriceps tendon or loosening of internal fixation during follow-up. At last follow-up, the active ROM of the knees was (121.0±7.9)°in flexion, showing no significant difference when compared with preoperative one (t=-2.075, P=0.058); the active ROM was (8.2±6.1)°in extension, showing significant difference when compared with preoperative one (t=11.702, P=0.000). Lysholm score was 84.6±12.4, showing significant difference when compared with preoperative score (t=-16.226, P=0.000). According to the American Knee Society score (KSS), the results were excellent in 4 sides, good in 9 sides, and fair in 1 side, and the total excellent and good rate was 92.9%. At last follow-up, the active ROM of the knee, Lysholm score, and KSS score were significantly better in young patients (<45 years) than in elder patients (≥45 years), and in patients receiving early operation (<2 weeks) than in patients receiving late operation (≥2 weeks) (P<0.05). ConclusionFor fewer traumas and early functional exercise after operation, the suture bridge technique benefits functional restoration of knee joint in uraemic patients. Operation chance and age seem to be important factors to the results. Early operation should be considered when quadriceps tendon ruptured.

  • Effectiveness comparison of arthroscopic intertubercular groove and open subpectoral tenodesis for long head of biceps tendon tendinopathy

    ObjectiveTo compare the effectiveness of arthroscopic intertubercular groove and open subpectoral tenodesis in treatment of long head of biceps tendon (LHBT) tendinopathy.MethodsA clinical data of 80 patients with LHBT tendinopathy who were admitted between June 2013 and May 2017 and met the selection criteria was retrospectively analyzed. After cutting LHBT under arthroscopy, the arthroscopic intertubercular groove tenodesis was performed in 40 cases (group A) and open subpectoral tenodesis was performed in 40 cases (group B). There was no significant difference in the gender, age, side of the affected shoulder joint, disease duration, and preoperative pain visual analogue scale (VAS) score, Constant score, American Society of Shoulder and Elbow Surgery (ASES) score, Disability of Arm, Shoulder, and Hand (DASH) score, LHBT score (LHBS) between the two groups (P>0.05). The operation time and the scores of shoulder joint pain and function at 12 months after operation were compared between the two groups.ResultsThe operation time was (3.6±2.5) minutes in group A and (8.5±2.3) minutes in group B, showing a significant difference (t=18.584, P=0.000). The incisions of the two groups healed by first intention, and there was no complication such as infection or thrombosis. All patients were followed up. The follow-up time was 24-30 months (mean, 26.0 months) in group A and 24-31 months (mean, 26.0 months) in group B. Both Speed test and Yergason test were negative at 3 months after operation. MRI showed that there was no obvious effusion around the LHTB and no dislocation of LHTB. At 12 months after operation, the VAS score, Constant score, ASES score, DASH score, and LHBS score of the two groups all improved when compared with preoperative ones (P<0.05), and there was no significant difference in the differences before and after operation between the two groups (P>0.05). No Popeye sign appeared during the follow-up.ConclusionThe arthroscopic intertubercular groove and open subpectoral tenodesis can effectively relieve shoulder pain and improve function, but the former has shorter operation time and less trauma.
